Kuramba kwe oxidation kwezvikamu zve ceramic zvakarurama uye nzvimbo yekushandisa kwayo
Zvikamu zveceramic zvakanyatsonaka zvinhu zvakakosha zvikuru muindasitiri yemazuva ano, uye hunhu hwazvo hwepanyama nemakemikari hwakaunza shanduko huru muminda yakawanda. Pakati pazvo, kuramba oxidation ndeimwe yehunhu hwakakosha hwezvikamu zveceramic zvakanyatsonaka, izvo zvinonyanya kukosha munzvimbo dzakaoma.
Kuramba kwe oxidation kwezvikamu zveceramic zvakarurama
Zvinhu zvakagadzirwa neceramic zvine hunyanzvi hwakakwana, zvakaita sealumina, silicon nitride, silicon carbide, nezvimwewo, zvinozivikanwa nehukuru hwazvo hweantioxidant. Zvinhu izvi zvinogona kuchengetedza hunhu hwemakemikari hwakagadzikana pasi pekupisa kwakanyanya uye munzvimbo ine oxidation yakawanda, uye hazvisi nyore kuita neoxygen, nokudaro zvichidzivirira oxidation, ngura uye kuora kwekushanda kwezvinhu. Kusagadzikana kwe oxidation uku kwakanyanya kunokonzerwa nechimiro chekristaro chakagadzikana uye simba rezvisungo zvemakemikari mukati me ceramic, izvo zvinoita kuti ikwanise kuchengetedza kugadzikana kwenguva refu uye kuvimbika munzvimbo dzakaoma.
Nzvimbo yakakosha yekushandisa
1. Ndege
Munzvimbo yemuchadenga, kuramba kuoxidation kwezvikamu zveceramic zvakanyatsonaka kwakakosha zvikuru. Injini dzendege nespacecraft dzinofanira kutsungirira tembiricha yakakwira zvakanyanya uye magasi anooxidation panguva yekubhururuka nekukurumidza. Zvikamu zvakaita semakamuri ekupisa, ma nozzles nema turbine zvakagadzirwa nezvinhu zveceramic zvakanyatsonaka zvinogona kuchengetedza kushanda kwakasimba patembiricha yakakwira, kudzivirira oxidation uye ngura zvinobudirira, uye kuona kuti injini nespacecraft zvinoshanda zvakanaka.
2. Chikamu chesimba
Munyaya yesimba, kuramba kuoxidation kwezvikamu zveceramic zvine hunyanzi zvine basa guru. Semuenzaniso, mumidziyo inodziya zvakanyanya senge magasi turbine nemaboiler anopfuta marasha, zvinhu zvakaita sezvikamu zve thermal insulation uye mafirita akagadzirwa nezvinhu zveceramic zvinogona kudzivirira kuputsika kweutsi hunodziya zvakanyanya, kuchengetedza chimiro chemukati chemidziyo uye kuvandudza mashandiro esimba. Pamusoro pezvo, mumunda wesimba renyukireya, zvinhu zveceramic zvine hunyanzi zvinoshandiswawo zvakanyanya mukupisa kwemafuta uye kudzivirira ma reactor enyukireya kuti ive nechokwadi chekushandiswa kwakachengeteka kwesimba renyukireya.
3. Indasitiri yemakemikari
Muindasitiri yemakemikari, maitiro akawanda emakemikari uye maitiro anofanirwa kuitwa munzvimbo dzinopisa zvakanyanya, kumanikidzwa kwakanyanya uye nzvimbo dzine ngura dzakasimba. Zvikamu zveceramic zvakanyatsonaka, zvine resistance yakanaka ye oxidation uye resistance yengura, zvinhu zvakakosha munzvimbo idzi. Semuenzaniso, mumidziyo yemakemikari ine ngura yakanyanya yeacid nealkali, zvikamu zvakaita semapaipi, mavharuvhu nemapombi akagadzirwa nezvinhu zveceramic zvinogona kudzivirira ngura nekubuda kwemvura zvinobudirira, zvichivimbisa kuchengetedzeka uye kugadzikana kwekugadzirwa kwemakemikari.
mhedziso
Muchidimbu, kuramba kwe oxidation kwezvikamu zve ceramic zvine hungwaru ndeimwe yehunhu hwazvo hwakanaka, hunoita basa rakakosha muindasitiri yemuchadenga, simba uye makemikari. Nekufambira mberi kuri kuramba kuchiita sainzi netekinoroji uye kuwedzera kuri kuramba kuchiita mashandisirwo, hunhu hwe antioxidant hwezvikamu zve ceramic zvine hungwaru hucharamba huchitarisirwa uye huchivandudzwa, zvichiunza hunyanzvi nekufambira mberi kuminda yakawanda. Mune ramangwana, nekufambira mberi kuri kuramba kuchiita sainzi yezvinhu uye tekinoroji yekugadzirira, tine chikonzero chekutenda kuti zvikamu zve ceramic zvine hungwaru zvicharatidza runako rwazvo rwakasiyana uye kukosha muminda yakawanda.
